Figure 5-3 Sub-Threshold Arcing: Arc/Out Of Regulation and Output Arcing LEDs

Arc/Out of Regulation LED
LED is normally off (i.e., clear)
•
Flashes yellow when subthreshold
•
arcing occurs and when the HV is
out of regulation
HV Out of Regulation LED
LED is normally green
•
Turns amber for 2 seconds each
•
time the Arc/Out of Regulation
LED flashes amber

Figure 5-4 Filament Load Fault and Filament Power LEDs

Filament Load Fault LED
LED is normally green when FPS
•
is powered up
Turns red to indicate an 'open'
•
on the filament circuit (i.e.,
filament broken or burned out;
resistance across emitter is 2.5
Ohms or greater)
LED is green when FPS is
•
powered up, red when FPS is
not powered up
The HV can remain on, even if the gun is switched off, either due to a fault or user
action.

Figures 5-6 through 5-10 point out and describe the front panel LEDs that indicate latching
0101-8292-0, Rev. C
Figures 5-4 and 5-6 through 5-10 do not show HVPS LEDs as they would
appear when the applicable faults have occurred. Instead, the LEDs
described in these illustrations are shown as red merely to highlight
them.
